<![CDATA[The purpose of this study was to describe the achievement of the triangular principle of junior high school students through YouTube-assisted learning during the COVID-19 pandemic. It is exploratory research. The subjects of this study were middle school students in Bengkulu City, Indonesia. We conducted task-based interviews with twenty-one people. The data from the completion of the task was analyzed early to determine their level of thinking. It was using its genetic decomposition. We classified them into five levels of schema development. We selected students who were at the trance level for further in-depth interviews. We use audio-visual recorders to get complete and accurate data. Data were analyzed by applying qualitative data analysis techniques. The results of this study were 19% of the research subjects were at the intra level, 33% were at the semi-inter level, 33% were at the inter level, and 10% of the subjects were at the inter level, and only one person who was at the trance level (= 5%). The conclusion of this study is that students who are at the highest level are able to build relationships between actions, processes, objects, and previous schemas so that a mature schema is formed about the area of the triangle.]]>

<![CDATA[Mathematical modeling appears today as a dynamic tool for teaching and learning mathematics, because it connects mathematics with real world applications thus increasing the student interest on the subject. In the present paper a method is developed that uses grey numbers for evaluating student mathematical modeling capacities and a classroom application is presented illustrating it. This new assessment method is useful in particular when the student performance is evaluated with linguistic characterizations (grades) and not with numerical scores, which makes non feasible the calculation of the mean value of those grades. Grey numbers are indeterminate numbers which are defined with the help of the real intervals and they have found nowadays many applications in real life, science and engineering for handling approximate data.]]>

<![CDATA[The aim of this study is describing students’ conception about mathematics as sensible based on personality types. This study is a descriptive study with qualitative approach. Subjects of this study are four female vocational students with guardian type, artisan type, rational type, and idealis type with equivalent mathematics ability and feminine gender orientation. The selection of subjects was held through personality test, mathematics ability test, and gender orientation questionnaire. The data were collected by giving problem solving task and task-based interview.The result showed that there are some differences on students’ conception about mathematics as sensible based on personality type. Students with guardian type, Artisan type, and rational type planed a problem solving strategy based on their previous experience, while student with Idealis type planed a problem solving strategy based on the mathematics concept related to the problem. Students with Guardian type and Rational type planed alternative strategy in solving problem to get better solution. Another difference is in explaining the reason of using strategy. Student with Rational type didn’t explain the reason of using the problem solving strategy]]>

<![CDATA[Reversibility is a mental process to construct two-way correlation from an initial condition to the result, and from result reverse to initial state. The concept of reversibility is a key aspect of the development of mathematics which is often problema for student. Reversible thinking is the primary requirement to solve mathematical problems. The importance of reversibility is one of the reasons in this study. The aimed of this study was to identify student’s reversibility in solving algebaic problems. The subject consisted of 32 junior high school student’s, especially at the eight grade. In this qualitative study, data were collected by a reversibility task and interview. The reversibility task contained simple equation. The result of this study indicate that reversibility aspect of solving algebaic problem can identified were reciprocity and negation, in this case reciprocity was more prominent. This could be seen from 32 junior high school students were able to make equation according to the reversibility aspect, but there were only five students are be able to fulfill two aspect of reversibility, described as negation and reciprocity, the others only fill reciprocity. The result showed that the problem related reversibility on junior high school still exist, especially in the aspect of negation.]]>

<![CDATA[This research and development aims to develop LKPD based on open-ended and test its effectiveness on critical thinking skills in mathematics. This development phase begins with research and information gathering, planning, initial product form development, initial field testing, major product revisions, and main field testing. The subjects of this study were the eighth grade students of Al-Huda Jati Agung Junior High School in the academic year 2019/2020. The effectiveness test was conducted to determine the effectiveness of LKPD on the ability to think critically mathematically. The LKPD based on the open-ended developed was suitable for use in the excellent category based on the results of the validation of two expert validators. Preliminary field trial results indicate that LKPD is included in the good category. Field test results show that the average increase in students 'critical thinking skills in mathematics using LKPD on an open-ended basis is higher than the increase in average students' critical thinking skills in mathematics that do not use LKPD based on open-ended, so it can be concluded that LKPD based on open-ended effective for improving students' critical thinking math skills.]]>
